Complementary and alternative medicine utilisation in NHS and private clinic settings: a United Kingdom survey of 400 infertility patients.

Some evidence suggests that complementary and alternative medicine (CAM) has found increased utilisation among patients seeking infertility treatment, although there is little information available to quantify this phenomenon. This is important information as there is marketing for CAM directed to this group and professionals need to be aware of the treatments their patients are receiving. Patients attending for infertility diagnosis and treatment often ask the physician about CAM; this paper seeks to compare the prevalence of CAM use among infertility patients in National Health Service (NHS) and private clinics. This paper provides results of a survey of couples (n = 400) divided equally between NHS and private settings. Our data suggest a high use of CAM particularly among female private patients, although patients appear sceptical of the efficacy of such treatment which is consistent with the literature.

Legal issues to address when managing clinical information across Europe: the ECIT case study (www.ECIT.info).

This paper identifies issues which will need to be addressed in pursuing the aims and objectives of the European Classification of Infertility Taskforce (ECIT), namely: to establish classification codes for infertility management; to improve the consistency of infertility information collection by specialist centres, particularly but not exclusively by computerised systems; to use these codes to enable the transfer of infertility information from specialist centres to national infertility data registries; to develop a Grid linking the data held in European infertility data registries; to use Grid processing to mine the data in the European infertility data registries to optimise patient management improving the effectiveness of treatment and reducing the risk.

European Classification of Infertility Taskforce (ECIT) response to Habbema et al., 'Towards less confusing terminology in reproductive medicine: a proposal'.

The European Classification of Infertility Taskforce (ECIT) has been formed by ESHRE to develop a set of infertility-related codes (descriptions, interventions and outcomes) appropriate for computerization (http://www.ecit.info). In this article, ECIT reflects on previous suggestions in this Debate series, agreeing with the weaknesses of the current terminology used in reproductive medicine. Although ECIT is enthusiastic about the extension of terminology, caution is raised in abandoning familiar terms that may lead to greater rather than less confusion. Instead, ECIT suggests a way forward using structured computerized statements to retain current terms but extend their meaning.

Can the Internet widen participation in reproductive medicine education for professionals?

BACKGROUND: Traditional campus-based models of education are unsuitable to many, particularly if in full-time employment supporting families, whereas the Internet now permits new models of education. Following an iterative process of development and evaluation in 2001, the University of Bristol launched a masters programme covering reproduction and development delivered principally over the Internet. METHODS: Students attend short biannual residential workshops and the rest of the course is delivered online. In 2003, the 20 active students were invited to complete a structured online questionnaire. RESULTS: The 18 students completing the questionnaire identified distance learning as the key factor in their course selection. Most students felt that residential workshops aided subsequent electronic communication. Discussion of ideas is an essential component of postgraduate courses and web-based discussion forums appeared to provide an acceptable medium for this. The use of web-based audio lectures and computer-assisted assessments was well received. Also these systems may reduce disadvantages overseas students encounter when completing assessments in their non-native language. CONCLUSIONS: The overall positive response from students (and their tutors) to using the Internet for multiprofessional reproductive medicine education is encouraging and has wider potential in the future.

Epidermal growth factor contamination and concentrations of intact human chorionic gonadotropin in commercial preparations.

It is well-known that many urinary-derived human chorionic gonadotropin (hCG) preparations contain a variety of contaminating agents that may influence the efficacy and possible safety of their application. Herein, we report the finding of epidermal growth factor (EGF) contamination and high hCG beta core levels in two leading brands of hCG - findings that will promote the use of recombinant hCG instead of the cruder, urinary-derived formulations.

Parenting infants conceived by gamete donation.

In recent years, concerns have been raised regarding the potentially negative consequences of gamete donation for parent-child relationships. Findings are presented of a study of families with an infant conceived by gamete donation. Fifty donor insemination families and 51 egg donation families were compared with 80 natural conception families on standardized interview and questionnaire measures of the psychological well-being of the parents, the quality of parent-child relationships, and infant temperament. The differences that were identified indicated more positive parent-child relationships among the gamete donation than the natural conception parents, accompanied by greater emotional involvement with the child. Comparisons were also carried out between the donor insemination and the egg donation parents on their experiences of gamete donation. In contrast to the findings of earlier investigations, the donor insemination and egg donation parents appeared to be more open toward disclosing the donor conception to the child. It was concluded that infants conceived by egg or sperm donation did not appear to be at risk for parenting difficulties.

Transient restoration of anti-viral T cell responses induced by lamivudine therapy in chronic hepatitis B.

BACKGROUND/AIMS: Lamivudine therapy in patients with chronic hepatitis B can induce the recovery of antiviral T cell responses. It is unknown whether the recovery of T cell responsiveness is long-lasting and persists throughout the treatment and whether the elevation of viremia which follows therapy withdrawal can restore a condition of T cell unresponsiveness. METHODS: Frequency and function of circulating hepatitis B virus (HBV)-specific CD4 and CD8 cells from 12 hepatitis e surface antigen + patients with chronic hepatitis B were studied longitudinally before, during and after lamivudine therapy by intracellular cytokine staining, proliferation and cytotoxicity assays against HBV proteins and peptides. CD4-mediated responses were analyzed in all patients, whereas CD8 cells were studied in 6 HLA-A2+ patients. RESULTS: HBV-specific CD4 and CD8 reactivity showed a bi-phasic behavior under lamivudine therapy with an early enhancement of T cell frequency and intensity of responses followed by a persistent decline starting from the 5th to 6th month of treatment. CONCLUSIONS: Since restoration of HBV-specific T cell reactivity is only transient, our study indicates that therapeutic stimulation of HBV-specific T cell responses to complement lamivudine treatment should be done early after the initiation of lamivudine. Moreover, the transient nature of the immune reconstitution may represent a favorable condition for virus reactivation once lamivudine therapy is withdrawn.

Serum vascular endothelial growth factor levels are poorly predictive of subsequent ovarian hyperstimulation syndrome in highly responsive women undergoing assisted conception.

OBJECTIVE: To determine whether serum vascular endothelial growth factor (VEGF) levels can distinguish highly responsive women who subsequently develop ovarian hyperstimulation syndrome (OHSS) from women with a similar ovarian response who do not. DESIGN: Prospective controlled study. SETTING: University IVF unit. PATIENT(S): Women undergoing IVF who met predetermined risk criteria for OHSS. Patients developing OHSS were compared with patients who did not develop OHSS. INTERVENTION(S): Long-protocol pituitary down-regulation followed by FSH stimulation by a standard protocol without coasting. A maximum of three embryos was transferred. Vaginal progesterone was used for luteal support. MAIN OUTCOME MEASURE: Occurrence of OHSS; serum VEGF concentrations on the day of embryo transfer (ET) and at 5 and 10 days after ET. RESULTS: Serum VEGF levels at any time point did not differ significantly between 9 OHSS cases and 9 controls. Vascular endothelial growth factor levels in samples collected from cases before the onset of OHSS were higher than levels in time-matched samples from controls (medians, 177.6 [range, 64.02-549.1] pg/mL vs. 100.7 [range, 37.59-246] pg/mL, respectively), but the difference failed to reach statistical significance (P=.0518), and there was considerable overlap between cases and controls. CONCLUSIONS: Serum VEGF levels in the luteal phase do not distinguish between high-risk women who subsequently develop OHSS and women with a similar risk profile who do not develop OHSS.

The prevalence of Chlamydia trachomatis in fresh tissue specimens from patients with ectopic pregnancy or tubal factor infertility as determined by PCR and in-situ hybridisation.

The prevalence of chlamydial DNA determined by PCR and in-situ hybridisation (ISH) in fresh tissue specimens (endometrium, fallopian tube and ovary) was investigated in 33 women presenting with ectopic pregnancy (EP), 14 women with tubal factor infertility (TFI) and 50 control patients from the UK and the West Indies. In the UK EP group, chlamydial DNA was detected by PCR in 56% of patients; similar results were found in the Trinidad EP group (67%). In the TFI group, chlamydial DNA was detected in (71%) of patients by PCR. The detection of Chlamydia trachomatis DNA by ISH was highest in the TFI group (43%). Women presenting with EP and TFI showed evidence of previous or current genital C. trachomatis infection, underlining the importance of this microorganism in the development of these conditions. Importantly, chlamydial DNA could be detected in DNA preparations from the endometrium, fallopian tube and ovary of EP and TFI patients at the time of surgery.
